Choleliths, commonly known as gallstones, in cats refer to the formation of solid material within the gallbladder. These stones can vary in size and composition, sometimes causing health issues for the affected cat.Here are some key points about choleliths in cats:

1. Formation: Choleliths can develop due to imbalances in the components of bile, such as cholesterol, bilirubin, and calcium salts. The exact cause isn't always clear, but factors like genetics, diet, and certain medical conditions can contribute.
2. Symptoms: Cats with choleliths might show signs of abdominal discomfort, vomiting, decreased appetite, and jaundice (yellowing of the skin and eyes). In some cases, they might not display any obvious symptoms until complications arise.
3. Diagnosis: A veterinarian might suspect choleliths based on the cat's symptoms and perform diagnostic tests such as ultrasound, X-rays, or blood work to confirm the presence of gallstones.
4. Treatment: Treatment options can vary based on the size and severity of the choleliths. In some cases, dietary management or medications might be recommended to dissolve smaller stones. Surgical removal of the gallbladder (cholecystectomy) might be necessary for larger stones or cases with complications.
5. Prevention: Preventative measures often involve dietary changes aimed at reducing the formation of gallstones. This might include a special diet low in fat or specific nutrients that contribute to stone formation.

Choleliths can pose serious health risks if they cause blockages or lead to inflammation or infection of the gallbladder. Therefore, prompt veterinary attention is crucial if a cat shows any signs of potential gallbladder issues.
